if you can tell you have high prolactin then you are fucked by then. (milking your tits, sex drive to shit)
you should be running anti-prolactin from day 1 of running tren.
grab some prami from chemical need, that will do the job. 3 day shipping..
i have no idea if that product you mention works, i have never tried it .. this is one thing I won't take a chance with.. BUT if you insist then pay the 44 bucks or whatever and get bloods a couple weeks after starting tren. and see what is up .. in the mean time grab the prami and have it ON HAND just in case
